CMAKE_<LANG>_ANDROID_TOOLCHAIN_MACHINE

在 3.7.1 版被加入.

When 為 Android 進行交叉編譯 this variable contains the toolchain binutils machine name (e.g. gcc -dumpmachine). The binutils typically have a <machine>- prefix on their name.

See also CMAKE_<LANG>_ANDROID_TOOLCHAIN_PREFIX and CMAKE_<LANG>_ANDROID_TOOLCHAIN_SUFFIX.
